Column installed insulation load switch, type PGS-12/24/40.5,is suitable for the rated voltage 12/24/40. 5kV,rated current 400A,630A,50/60Hz power grid open circuit,load current in closed Power system,overload curren. This load switch can separate those broken distribution line automatically.
With the latest technology, it has the newest electronic controller.The switch can be used by manual operation, electric operation and operation from a long distance. Electronic controller is installed in a stainless steel cabinet which is suitable for using under all kinds of climatic conditions. In addition, there are some wired and wireless modem installed in the cabinet through which it can realize the remote monitoring and control. Simple installation on column is convenient, fast, and also can reduce the construction cost.

1. SF6 gas-insulated
1.1 SF6 gas is a kind of nontoxic, nonflammable and electrical insulating gas. It has the excellent characteristic of arc extinction.
2. Drivepipe with large diversity
2.1 In addition to the standard ceramic drivepipe, we can also provide a variety of solutions, including rubber insulators used in the epoxy resin filling equipment
3. Visible open / closed status
3.1 It is easy to see the main contact position indicator which is color-coded just standing on the ground (Green - off; red - closed). The indicator is directly connected with the main contacts of the drive shaft assembly to ensure accurate display of contact states.
4. Quick operation
